Full-Stack Developer
I design and build web platforms that run in real production — and operate the Kubernetes cluster they run on.
01 · Who I am
I am a developer, educated at the HTL Leonding, where several of my projects grew from coursework into software that is used in production every day.
My diploma thesis ArtAdmin was created in cooperation with Stift St. Florian, and the registration platform I built for the HTL Leonding is actively used by students applying to the school.
Beyond application development I run my own Kubernetes home server: it is the production environment for personal services like Nextcloud and Vaultwarden, and at the same time my development environment for new coding projects.
I enjoy working across the whole stack — from databases and backend services to frontends and the infrastructure underneath them.
02 · What I work with
Languages, frameworks and tools I use — from frontend to infrastructure.
03 · What I've built
Software that runs in production — for a school, a monastery and my own infrastructure.
Art administration platform for Stift St. Florian
My diploma thesis, developed in cooperation with Stift St. Florian. ArtAdmin digitizes the administration of the monastery’s art collection — from cataloging artworks to managing their data in one central, searchable system.
The official registration platform for new HTL Leonding students
A web platform for the HTL Leonding that handles the registration of prospective students. It is actively used in production by every new student who wants to join the school — real users, real data, real responsibility.
Self-hosted production and development environment
My own home server running Kubernetes. It serves as the production environment for my personal services — Nextcloud, Vaultwarden and more — and doubles as the development environment for my coding projects. Infrastructure as a hobby, operated for real.
Server calculator for my local firefighter festival
A smaller practical tool built for my local firefighter fest: a calculator that helps the team with the calculations needed when running the festival — built to make a real event run smoother.
